Safety first

You want to be careful out there. These tools will help you stay safe and secure.

SMART ALARM There’s nothing like the panic that sets in when a smoke alarm goes off. Nest Protect smoke plus CO alarm helps calm jangled nerves by sending an alert to your phone that tells you exactly where the problem is. You can silence the alarm from your phone—no broom handles needed to stop the noise. $119. (855) 469-6378; nest.com.

CANDID CAMERA Your word against another driver’s? A video record could clear things up. The Magellan RoadMate 6230-LM is more than a GPS—it’s also a dash-mounted camera that records wide-angle video of action around your car while you drive. In case of a collision, a lock feature preserves the video and data. $161. (800) 720-5537; magellan.factoryoutletstore.com.

WHO’S THERE? A peephole is fine, but you have to walk all the way to the door to use it. With the Ring Video Doorbell, just glance at your smartphone to see who’s standing at the door—whether you’re home or not. You can have a conversation, too. Night-vision capability means you don’t have to leave the porch light on. $199. (800) 656-1918; ring.com.

THROW AWAY THE KEY Tend to forget your house key? No spare under the mat?
